On the other hand, another PSMA PET imaging study of 37 patients, including 14 cases of metastatic castration-sensitive and 23 cases of castration-resistant prostate cancer, carried out by Mena et al., showed a lower level of PSMA uptake for early castration-sensitive patients on short-term ADT compared to those with advanced disease and long-term ADT [22]. The gene discussed is FOLH1; the disease is prostate carcinoma.
